This video will show you one of the ways to properly charge a R-290 system. Before charging, you must make sure the refrigerant you are using is refrigerant grade R-290 propane and not standard propane that would be used for a gas grill. In this video this system has already been repaired, and the dryer has been replaced. Before you begin any hydro-carbon refrigeration repairs, it is recommended that the repair is done in a well ventilated area, all ignition sources have been extinguished, the HC leak detector is turned on for the whole duration of the repair, and the safety placard is in the area where the repair is being made. After your vacuum has been pulled to 500 microns, shut off the valves at the low side process and high side process tubes. And then shut off the valve at the vacuum pump. Remove the hose from the vacuum pump, and set the 1 lb. tank of R-290 on its side and onto the scale. Connect the charging hose to the tank's adapter, and open the tank's valve. Then bleed the hose connection. Place something heavy on the charging hose so that if the hose gets pulled, it will not affect the scale. Open the charging hose at the tank. Zero out the scale. At the high side valve, open the valve, and then close it when the desired charge has been weighed in. If the high side did not fully charge, start the compressor and open the low side valve to finish the charge. Then, close the valve, and leave the valves closed. Before removing the hose, pinch off the process line. Remove the hoses and the valves. Use the bubble solution to make sure that the pinch-off tool is tight enough and that no refrigeration is leaking out. Braise the line closed. Repeat for the other process line. You can bend any remaining charges in the hoses. Make sure to do this away from any ignition source and in a well ventilated area.
